HGST, now a Western Digital company, today introduced the first 4TB enterprise-class hard drive family, the Ultrastar 7K4000.

Ushering in a new generation of 512e Advanced Format
drives, the Ultrastar 7K4000 family provides
space-efficient, high-performance, low-power storage. As
the only 4TB 7,200 RPM enterprise-class drive in the
industry, and one with a 2.0 million hours mean time
between failure (MTBF) specification, the Ultrastar
family is aimed at 24x7 enterprise applications such as
big data, cloud computing, data warehousing,
video-on-demand, disk-to-disk backup, and massive
scale-out storage implementations.

The 4TB Ultrastar 7K4000 drive delivers 33 percent more
capacity in the same 3.5-inch footprint at 24 percent
lower watts/GB than its predecessor, the 3TB Ultrastar
7K3000 drive. Now IT managers can get 2.4 PBs in the
footprint of a standard 19-inch storage rack by stacking
ten 4U, 60-bay enclosures. The Ultrastar 7K4000 family
can also help datacenters achieve lower AC power and HVAC
requirements. With five Advanced Power Management modes,
the Ultrastar 7K4000 achieves a 59 percent reduction in
watts from peak usage during low RPM idle mode, and uses
less than 1W during standby/sleep modes.

The Ultrastar 7K4000 family features a 6Gb/s SATA
interface and a 64MB cache buffer. It is an Advanced
Format drive, using 4096-byte sector size, and is
backward compatible with legacy 512-byte sector size by
offering built-in 512-byte emulation through the SATA
interface.

Other features include a Dual Stage Actuator (DSA) and
Enhanced Rotational Vibration Safeguard (RVS) and a bulk
data encryption (BDE) option to help keep information
safe.

HGST?s new 7,200 RPM Ultrastar 7K4000 drive family, which
comes in 4TB, 3TB and 2TB capacities, is covered by a
five-year limited warranty.
